ACQUISITION OR DISPOSITION OF ASSETS. On May 11, 2001, Clover Acquisition Corp. ("Merger Sub"), a wholly owned subsidiary of LSI Logic Corporation ("LSI Logic"), acquired approximately 43.6 million shares of common stock of C-Cube Microsystems Inc. ("C-Cube") (including shares tendered through notice of guaranteed delivery) equaling approximately 86% of the total number of outstanding shares of C-Cube common stock. These shares were acquired pursuant to the exchange offer (the "Offer") by Merger Sub for all of the outstanding shares of C-Cube common stock at an exchange ratio of 0.79 of a share of LSI Logic common stock for each share of C-Cube common stock that was validly tendered and not properly withdrawn. The initial offering period expired at 12:00 midnight, New York time, on Thursday, May 10, 2001. After the expiration of the initial offering period, LSI Logic elected to provide a subsequent offering period in connection with the Offer (the "Subsequent Offering Period"). The Subsequent Offering Period began at 9:00 a.m., New York time, on May 11, 2001, and will expire at midnight, New York time, on Thursday, May 24, 2001. During the Subsequent Offering Period, LSI Logic will accept for exchange and exchange each share of C-Cube common stock that is validly tendered for 0.79 of a share of LSI Logic common stock, which is the same exchange ratio offered for shares of C-Cube common stock tendered prior to the expiration of the initial offering period, promptly after such C-Cube shares are tendered. Shares of C-Cube common stock tendered during the Subsequent Offering Period may not be withdrawn. After the expiration of the Subsequent Offering Period, LSI Logic intends to complete the acquisition of C-Cube by merging Merger Sub into C-Cube, after which C-Cube will be a wholly owned subsidiary of LSI Logic.
